With the correct litter box, the cat will be able to do its business not on the floor but on the litter box, cutting the time spent on wiping the floor down with any rag they could find at home. 

One factor that could be why a cat refuses to use the litter box is that it is too small. When it comes to litter boxes, one size does not fit all, significantly as a cat grows bigger and longer from nose to tail.

Average Litter Box Dimensions 

Average litter box dimensionsIn general, most cats won’t mind their litter boxes, but some will be picky enough never to use theirs at all. If this sounds like any cats pet owners have, they first need to consider whether the litter box is too short for their cats. Squeezing into a too-tight litter box is an uncomfortable ordeal that will make them give up on doing number one or two in the designated area. 

The average litter box available widely is the commercial litter box with a length of 20 inches or 51 centimeters. This box is not enough for cats that are 18 to 20 inches or about 46 to 51 centimeters long from the tip of their nose to their tail tip. 

On average, cats 18 to 20 inches or 46 to 51 centimeters should have a litter box at least 35 inches or approximately 89 centimeters long. Seeing the disconnect in these numbers, it is safe to assume that most commercial litter boxes are too small for a cat of average length. 

Kitten Litter Box Size 

Kitten litter box sizeA cat owner will need kitten litter boxes for all their baby cats. Choosing the correct box for a kitten is more straightforward because, most of the time, it will consider factors such as the kitten’s age and how long any cat owner will want their kittens to utilize it.

Generally, any litter box will do, but some want to look for the right one to ensure the highest comfort possible. The all-around rule of thumb is to go for a kitten litter box with a height of about 3 to 4 inches or 8 to 10 centimeters. This height will work perfectly for any kitten’s shorter legs. 

Another golden rule in choosing is ensuring that the kitten litter box will be shallow enough to accommodate at least 1.5 to 2 inches or 4 to 5 centimeters of cat litter. This will ensure the stability of the box so it will not topple over as your cat moves in and out of the litter box. 

What Size Litter Box For Cat? 

Even if a cat does business in a backyard, the smartest thing to do is purchase a litter box inside the home to ensure that they get an area to safely and cleanly go indoors.

Cats are notoriously clean and will get stressed out if their litter is dirty for extended periods, so if a home has more than two cats in the household, it is wiser to get each of them their litter box. 

To pick the right size, it is safe to opt for a litter about one and half times the size of a pet owner’s cat with a width that is at least or slightly bigger than them.

Measuring the length will entail a quick measurement from nose to tail. In general, it will be better to pick a larger cat litter box than getting the wrong size too small.
